advanced options

It is possible to build more than one index at a time with BuildVPIndex using the following options:

option meaning
-sm size of smallest index
-la size of largest index
-st step size of index

When using the advanced options, the size of the index will be appended to the given index name for each index.

*When building an index over sequences, each sequence is broken up into sets of overlapping fragments, or k-mers. For more information on this methodology, see the paper: ...
